CONVEYING SYSTEM.

To all whom it may concern:

Be it known that I, FRANCIS LEE STUART, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements {in Conveying Systems, of which the following is a specification.

This invention relates to conveying systems, in which material, such as coal,-is received from carriers, such as boats, ships, or other vessels, and conveyed to places of storage, where it is delivered and from which This system is shown in the accompanying v drawings, in which:-

Figure 1 is a plan view of the system.

Fig. 2 shows a transverse section on the line 22 of Fig. 1.

Fig. 3 shows a longitudinal section on the line 33 of Fig. 1.

Fig. 4 shows across section on the line '44: of Fig. 1, and

Fig. 5 is an end apparatus.

A, A indicate vessels which bring material to the dock B, along which are placed a plurality of railway tracks C. Unloading elevation of partof the apparatus D is mounted to move for to be shifted from place to place on tracks (l running parallel with the edge of the dock. The unloading apparatus may be of any suitable construction to lift the material I from the vessels and deliver it to suitable conveyers or carriers. As shown, the apparatus comprises-a frame supported on the tracks (Z and provided with an extensible arm or boom e carrying an elevated bucket E. The boom may be extended or retracted so as to deliver either to the hopper e or to other vessels A lying along-side the vessels TA, A. By means of the extensible boom the bucket or gathering device E may be placed over different parts of a vessel or may be "arranged lILPIOPBI position relatively to vessels that vary in distances from the Specification of Letters Patent ,Patented lVIar. 30, 1920.

dock. Material delivered by the bucket E to the hopper 6 may be delivered by said hopper to cars F on the tracks C. Prefer-' ably the hopper is provided with weighing devices of well known construction. Or

the material may be delivered to-' trucks or cars G running on a track 9. These cars or trucks may carry the material to any desired distant place. When, however, it is desired-to convey the material to places for storage in a plant, the material is delivered through a hopper H to a 'conveyer it running parallel with the edge of the dock. This conveyer It delivers to another conveyer J, which in turn delivers to a conveyer K running longitudinally through the plant. On opposite sides of the conveyer K there are storage spaces or areas on which piles of material L, L may be formed: Material is delivered from the conveyer K to the storage spaces b means of a delivery ap- J paratus M of well known construction .pro-

vided with a tripper M and with a deliver-= ing boom M The deli 'ering apparatus travels on tracks A parallel with the belt K. By such apparatus material may be piled as indicated at L. L on both sides of the main conveyerbelt K. The delivering apparatus may be moved back and forth on the track 7. so as to deliver at any desired place longitudinally in the storage spaces. N indicates a reclaiming apparatus of well known construction which travels on the track k and may be operated to gather material from either of the piles L, L and deliver it to a feeder 0, also traveling on the track Z". This reclaiming apparatus may be turned about a vertical axis so as to gather ,material from the piles and. deliver it to the feeder O, which may be shifted from place to placewith the reclaimer' as circumstances require.

Material which cannot be gathered from .the piles by the reclaimer N. is placed within its reach by locomotive cranes P, P or similar apparatus; which are mounted to move over tracks gjand 7? parallel with the track L. The tracksjg and p may be of standard gage and these tracksmay be used when desired to support railway. cars or trucks of ordinary constructlon-whlch may receive material and convey it to distant points.

It will be understood that 'thedelivering apparatus M maybe employed to make the piles L, L or'it may be used to deliver ma,-

terial received by the belt K either from the vessels or from the piles to other conveyers or carriers. As shown in the drawings, the delivering apparatus M may be moved to the end of the track is (Fig. 1) and its extensible boom M may be placed to deliver the material to a hopper Q which discharges onto a conveyer R, housed in an elevated structure S and delivering to a crusher T, where the material is broken to the desired size or grade and then passes to a conveyer U by which it is transferred to a screening machine V, where the screen w divides the material into different sizes or grades. The screened material passes to bins W provided with gates w, by which the delivery of the material may be controlled. When a suflicient quantity of material has accumulated in the bins, it is delivered to the conveyer belt X which carries it to storage bins Y from which it may be delivered when required, either to cars 2 g. 4) which may be weighed on scales Z and which may convey the material, such as coal, to any desired place.

y this system, material received in vessels may be distributed in various ways. It may be delivered to other vessels or to cars or trucks which convey it to distant points, or it may be placed in open storage areas, or it may be taken from vessels or from the storage areas, crushed or sub-divided when gates with which the slons, and provision desired,-\screened, and placed in bins or receptacles from which it may be discharged onto trucks for city use or onto other car.- riers which convey it to distant points. The bins Y are elevated in the manner indicated in Fig. 4 sothat the trucks Z may pass under them and receive materialth rough' the bins are provided. As indicated in Fig. 1, the trucks Z may ass under the bins in the'direction indicate by the arrows and then pass out and over the scales Z without interference, the trucks entering in one path and passing out and on in another path. The piles of material in the storage areas may be of large dimenis-made, as has been before explained, for athering material in places remote from tilie reclaiming apparatus, and placing it within reach of such apparatus so that the piles may be cleaned up quite thoroughly when the supply is reduced. This last mentioned feature of the system has been found to be ofgreat practical importance.

I claim as my invention 1. A conveying system for receiving and delivering material, comprising unloadin apparatus .by which material is gather d from vessels or other. carriers, conveyers for carrying material to storage spaces, means for transferring material from the unloading means for forming piles ot material In sald.
